How $1,000 grows at 5%
Compound interest earns returns on your returns — not just your original investment. At 5% per year, your money doubles every 14.4 years (the Rule of 72). Over 10 years, that compounds to a 1.63× multiplier.
In year 1, $1,000 earns $50 in interest. By year 10, the annual interest has grown to $78 — because each year's interest is calculated on a larger balance.
